SamTrans operates 76 bus routes throughout San Mateo County and into parts of San Francisco and Palo Alto.  It began operating bus service in 1976 after consolidating 11 municipal transit services in the county into a coordinated network.  In mid-1977, SamTrans inaugurated its mainline service from Palo Alto to San Francisco, previously operated by Greyhound.

Over the years, SamTrans has introduced improved vehicles, such as hybrid and low-floor buses.  It also has adjusted coverage area and service in response to customers' travel patterns and available resources.
